Geophysical Survey Gravity surveying measures the change of rock density by looking at changes in gravity. This technology is used mostly in the Minerals, Coal and Oil and Gas industry.
Gravity surveying provides geophysicists, geologists and exploration managers with a picture of the sub-surface geology of a surveyed area, so they can see what’s underground.
The processed gravity maps define regions of rocks and minerals with differing densities by assigning colours along a colour ramp where the red end of the spectrum indicates more dense rocks and the green end indicates lighter rocks. Interpretation of this data helps geologists and geophysicists gain an understanding of what mineral types and resources may be found in surveyed areas.
